IMPROVEMENT IN GRAIN-DRILLS.

- Specificationforming part of Letters Patent N0. 196,652, dated October30,1877; application filed March 12,1877.

To all whom it may concern:

regulated quantities is fed fromthe hopper to the drill-teeth, and itsscope will be indicated distinctly in the following specification andclaims.

In the annexeddrawings, making part of this specification, Figure 1 is arear elevation; Fig. 2, a plan and horizontal section; Fig. 3, avertical transverse .section, and Fig. 4 a perspective view of thebracket which controls the adjustment of the seed-wheel.

The same letters are employed in all the figures in the indication ofidentical parts.

The grain is carried in a hopper, A, having holes in the bottom, underwhich are hung seed-cups,made in two parts,B B, curved and convergingtoward the mouth, in which is placed the wheel 0 and arm D of thebracket D, which slide longitudinally in the mouth.

. The wheel is longitudinallyfluted, and slides in and out through theside of B of the seedcup, passing through the annular plate 0, which isformed to conform to the fluted roller,

and revolves freely in a recess in plate 13,

formed to receive it, thereby supportin g the wheel 0, so that it canrotate and move longitudinally. The other end of the wheel 0 issupported by and slides freely on the tubular bearing B which is formedby the part B of the cup, where it is drawn in around the shaft, asclearly shown in Fig. 2. The wheel 0 is thus supported at both endsindependently of the square shaft E, which passes through it.

The end of the fluted feed-wheel runs in contact with theedge of the armD of bracket D, which slides in a groove out in plate B, and closes somuch of the mouth of the seed-cup as is not closed by the fluted wheel0. The wheel being placed between the arms D D of the bracket D, as thelatter is moved one way or the other, it carries with it the feed-wheel.In this manner the quantity of grain supplied is regulated by theposition of the fluted feed-wheel in relation to the throat of theseed-cups. This adjustment is effected by means of the sliding bar F, towhich the bracket is attached, and which is actuated by the lever G,bolted to it by a roimd bolt, and which, when the feed- Wheel isproperly adjusted, may be held in proper position by the thumb-nut G,confining the lever to a segmentally-slotted plate.

To indicate the proper opening for the seedwheel, a plate, H, isattached to bar F, and has a series of points placed opposite acorresponding series of graduated marks on plate I, made to indicatewhat is a proper opening for diiferent kinds of grain, such as wheat,oats, barley, &c.

What I claim as my invention, and desire to secure by Letters Patent,is-

1. A feed-cup for seed-drills, having on one inner side a tubularjournal or bearing, B cast on or rigidly attached thereto, whereon thefeed-wheel both rotates and slides axially,

as set forth.

2. In combination, a feed-cup having on one inner side a tubular journalor bearing, B cast on or rigidly attached thereto, and on which afeed-wheel both rotates and slides, and in the other side a ring ordisk, through which said wheel passes, as set forth.

3. The combination of the feed-cup, having on one inner side atubularjournal or bearing, cast on or rigidly attached thereto, and on whichthe feed-wheel both rotates and slides, the sliding bar, and brackets,for the purpose of moving said wheel on the line of its axis,substantially as specified.

In testimony whereof I have signed my name to this specification in thepresence of two subscribing witnesses.
